Both tenecteplase and alteplase are federally approved for use in dissolving clots in blocked heart arteries. But the newer drug tenecteplase is also being used by clinicians, off-label, to treat ischemic strokes, because clinical trials in stroke suggest that it may be at least as good as alteplase and it is easier to administer.
